The Queen will formally open a new elephant centre at Whipsnade Zoo today.
She'll be joined by the Duke of Edinburgh and is due to formally unveil a special plaque.
The £2m centre will house the zoo's herd of nine Asian elephants.
Loss of habitat, human conflict and poaching have caused the Asian elephant to become endangered.
The zoo is working in Thailand, where there is a large population of the elephants, to help reduce human wildlife conflict.
Her Majesty and His Royal Highness will meet zookeepers and vets, before visiting the amphitheatre for the official opening.
The enclosure will provide a host of elephant friendly features including:
- Soft sand flooring for comfort
- Dimming lights to mimic night-time conditions
- Feeding pods to release food regularly during the night
- Six oak trees for scratching posts.
It will also feature a viewing platform for visitors, all set in 20 acres of grass paddocks.
